About this part

Brand: Caterpillar (CAT) Part Number: 8N3325 Product: Exhaust Rocker Arm Assembly Engine Application: Caterpillar 3304 / 3306 diesel engines Cross-Reference Part Numbers: 5S6855, 8N3324, 9N5980

The Caterpillar 8N3325 exhaust rocker arm is a critical component of the valve train assembly in 3304 and 3306 diesel engines. It functions by transferring the motion from the pushrod to the exhaust valve, allowing for proper engine breathing and exhaust gas release. Owners typically replace this part when the contact surface shows signs of excessive wear, pitting, or if the internal bushing has developed play that affects valve timing and engine performance.

Before you order, please verify that the part number 8N3325 matches your existing component. You should also cross-reference this with part numbers 5S6855, 8N3324, or 9N5980 to ensure compatibility with your specific engine configuration. New, open box condition. Ships from Kansas City, MO with tracking.
